Event Reconstruction, of the signals from all the detector components in 512-ns event window with 125-MHz or 500-MHz sampling ADC’s. For the first step, we extracted energy and time information of the activities in the detector components from the waveforms (Sect. 4.1). Then, using the energy and time information from e

Analysis of the , and , Searches, cut-based analysis. We imposed event selection criteria (cuts) on the data set based on the CsI calorimeter information and activities in the veto counters. We optimized the cuts to obtain larger signal acceptance and smaller background events. After all the cuts were imposed, remaining events in t
